Back when this thread was active, I was short on time and frustrated that the machine shop was delaying every darned thing they could on the engine machining. As mentioned in my HH120 rebuild thread, I ended up taking on the rest of the machining or it would never have been completed before the machine shop went out of business.
The point is, I didn't have time or patience for the wheel bushings for awhile. So I looked at the extra wide wheels, ribbed Sears tires and moon wheel covers and figured these were probably the original 1968 Sears Super SS12 wheels. Here is a picture:
Being short on time back then and very frustrated by the massive waste of time by the machine shop debacle, I just went ahead and ordered the bushing set that was cross-referenced to the original Sears PN figuring it wasn't much money and I'd rather not have to do the messy teardown twice.
In checking the wheels today before disassembly, the rattle fit was worse than I originally estimated. The one side was flopping laterally maybe 3/4" or more; the other side was in excess of 1 inch. Was holding my breath figuring the spindles must be shot.
The bushings fit the wheel hubs perfectly and the spindles were at least as good as what I see being sold in eBay as "good usable". With this kind of apparent neglect, I am amazed the spindles weren't wrecked. Must be really tough stuff.
I cleaned and polished any minor scoring on the spindles so those areas would be less likely to chew up the new bushings.
The only near screw-up on my part was I FORGOT that I had read in here that a 68 Super would have a reverse thread bolt in the left front (I wonder if that is why so many LF spindles in eBay have the bolt snapped off and stuck in the threads?). That is LF from the perspective of the operator. The only thing that saved it was: I used one of the standard procedural steps for what appeared to be a stuck bolt - that being trying turning it the other way and VOILA! The truth was revealed. Due to earlyheimers being in good supply in my garage and figuring it could hide under the Super wheel cover, I did this:
As I'm sure the veterans in here know, with the right parts, the bushings are an easy job but a bit grungy at times - and a lot of cleaning. After pumping the newly bushed & installed wheels full of grease, I greased the kingpins and triangle radius link while I was there. It took a lot of grease to push out all the grime and ugliness in those 3 - especially that triangle thing. I'm betting that last had never been greased since the tractor was new.
I used the green synthetic polymer waterproof grease because it was what was in the gun.
The wheel bushings have very little radial play in them now. I'm thinking the tractor will be more predictable on side hills now.
Maybe it was wheel toe-in, but before replacing the bushings, the steering still felt ok for tightness except on sidehills. Go figure.
Thanks again to all,
